好砖,做台阶用: 你的回贴启发了我,问题解决了: Send portlet name to server, and server sends name back to browser !!!. So for example, see the post I attach here, if you click business name,

nicetomeetyou(_)
customer review and business info will be retrieved independently using the same ajax function sets.

    • check JSON. it is something like . in java. Ex: People.run= thisRunFunction(){} -michaellucad(michaellucad); 2009-1-9 (#4972883@0)
      • 果然有高人。再请问一下所有浏览器都直接支持JSON吗？还是要加载一些framework? -yesiam(party time); 2009-1-12 (#4976841@0)
    • 蠢猪，这都不会？不会没关系，Google该会吧？算了，今天大爷我高兴，教你娃两把刷子。新创建一个叫sorttable的对象（object instance 懂不？）。这个对象有三个属性init，makeSortable 和 guessType，并且这三个属性都是函数（function）。 -forevermore(Forever); 2009-2-11 {295} (#5043636@0)
      调用函数举例：

      sorttable.guessType(table, column);

      冒号是创建新对象时用来给属性赋值的。例：

      var stupidObject = {
      name: "yesiam",
      nickName: "party time",
      age: 21,
      gender: "male",
      saySomthing: function {
      alert("I'm really stupid");
      }
      };
      • mark -anthonylo2008(anthonylo); 2009-2-12 (#5043968@0)
      • 你这个sorttable跟后面的stupidObject有什么关系啊？小的要问错了，大爷你莫怪.. 小的自动自觉call 100次stupidObject.saySomething(). -anthonylo2008(anthonylo); 2009-2-12 (#5046075@0)
        • LOL. 没关系。sorttable是他的原例，后面的是我举的蠢例，包括普通属性和函数，更像一个通常用到的对象。 -forevermore(Forever); 2009-2-12 {638} (#5046358@0)
          既然你如此好学，我就在多说几句吧。以上stupidObject 对象有可以用下面几句话来产生：

          var stupidObject = new Object(); // 或者最简单 var stupidObject = {};
          stupidObject.name = "yesiam"; // 或者 stupidObject[name] = "yesiam";
          stupidObject.nickName = "party time";
          stupidObject.age = 21;
          stupidObject.gender = "male";
          stupidObject.saySomthing = function() {
          alert("I'm really stupid");
          };

          // 前面举例时忘了function后的括号（）

          想学好JavaScript，还是花点银子去买本书吧。只有一本书值得推荐（其它的都是垃圾）：JavaScript: The Definitive Guide

              • 大板砖尽管砸! 今年我要铺后院. You can only issue ajax call once at a click. that ajax call has to handle refresh for all components you want. Inside one html body, ajax is not designed thread safe !!! -nicetomeetyou(_); 2009-2-13 {63} (#5047304@0)
                initRequest(), req.onreadystatechange,,,, they are all globals.
                • You can only issue ajax call once at a click. -- 为什么？这跟你上面说的又有什么关系？没有那些狗P函数，没有click也能做很多事情。这就是我之前说你“简单问题复杂化”的原因。 -bdbs(别的不算); 2009-2-13 (#5047362@0)
                  • +1砖. what i want to do is server dynamically assigns number of to-be-updated portlet's names to a click event when builds a html page, so I want ajax funcs to be written as general as possible, you know framework template is complicated...? -nicetomeetyou(_); 2009-2-13 {208} (#5047375@0)
                    when framework is well built, any app can be built by designing style sheets and one can be done within a day. I can then hire designers with basic html skills instead of programmers, who cost more of course.
                    • "server dynamically assign ......" AJAX的作用是pull (from the server)，不是(server) push (to the client)！ -bdbs(别的不算); 2009-2-13 (#5047387@0)
                      • You are so out !!! I am saying dynamically creating ajax code on server side before it was sent to client !!!! -nicetomeetyou(_); 2009-2-13 (#5047392@0)
                        • 圈子越绕越大，越绕越远。真是吃饱了撑的。没话讲。 -bdbs(别的不算); 2009-2-13 (#5047439@0)
                • "they are all globals", i feel a little bit different. the reason is the secod callback object overwrite the first one. to fix this, this artical will help. -c1xwy(洪兴罩俺去战斗); 2009-2-13 (#5047444@0)
                  • 好砖,做台阶用: 你的回贴启发了我,问题解决了: Send portlet name to server, and server sends name back to browser !!!. So for example, see the post I attach here, if you click business name, -nicetomeetyou(_); 2009-2-13 {100} (#5048355@0)

            • 又要XB自己造的函数库了？唉～～～ -bdbs(别的不算); 2009-2-13 (#5047355@0)
      • you are so mean. -informix(informix); 2009-2-13 (#5046840@0)

    • In JavaScript, this is called Object literal. A way for creating an object. -xiaojh(提木霍顿); 2009-2-13 {403} (#5047526@0)
      eg.
      var point = { x:0, y:0 }; // Create object point which with 2 properties

      So for your codes, it means create a sorttable object, and it has many methods like guessType, makeSortable ....

      It is core JavaScript, all major browsers support it.


      sorttable = {
      init: function() {
      .....
      },

      makeSortable: function(table) {
      .....
      },

      guessType: function(table, column) {
      ....
      },
      ..
      }
